The Wikimedia Foundation's Analytics Engineering team is part of the Technology department.

The Analytics Engineering Team's primary responsibility is to "empower and support data informed decision making across the Foundation and the Community".

We make Wikimedia related data available for querying and analysis to both WMF and the different Wiki communities and stakeholders.

We develop infrastructure so all our users, both within the Foundation and within the different communities, can access data in a self-service fashion that is consistent with the values of the movement.

We keep all our documentation here on Wikitech. See also this FAQ
